Soil pollution remediation technology refers to the technology that USES chemical, physical and biological technologies and methods to reduce the concentration of pollutants in soil, fix soil pollutants, transform soil pollutants into low or non-toxic substances, and block the transfer channels of soil pollutants in the ecosystem.
At present, there are several kinds of remediation technologies, such as phytoremediation, microbial remediation, chemical remediation, physical remediation and comprehensive remediation. Some remediation technologies, such as the remediation of biodegradable organic pollutants and heavy metal contaminated soil, have entered the field application stage and achieved good results. It is of great significance to repair contaminated soil, prevent pollutants from entering the food chain, prevent harm to human health, and promote land resource protection and sustainable development.
With the increasingly prominent problem of soil pollution that endangers ecological safety and human health, the remediation of soil contaminated by persistent toxic substances, such as heavy metals, pesticides, persistent organic pollutants and organic metal compounds, has become a research focus in the field of soil science and environmental science. It is a trend of international soil remediation research and development to develop suitable risk assessment theories and methods of soil pollution and remediation as well as low-cost soil remediation technologies suitable for large-scale application.
The directional research on soil pollution remediation in the future may be carried out in the following aspects:
(I) site soil pollution diagnosis, trace toxic pollutant identification and source analysis, including: chemical, biological and ecological toxicology diagnosis of soil environmental combined/mixed pollution, soil environmental quality index, monitoring and identification of new trace toxic pollutant, pollution source identification and analysis methods, etc.
(2) of contaminated sites, soil pollution risk characterization and repair decision support system, including: the morphological and biological effectiveness of soil pollutants, the spatial distribution characteristics of soil pollution, pollution of soil under different land use modes of ecological and health risk assessment, risk priority repair point determination method of repair decision support system, lower costs for the environmental benefits - "risk" evaluation model of the trinity, etc.
(3) soil pollution repair process, mechanism and management, including: the repair contaminated soil bioremediation, physical, chemical remediation and joint repair process and mechanism of the natural ease the repair process and mechanism of repair process conditions, the effect of instruction and evaluation standard, soil restoration principle and specification of soil restoration policies, laws and regulations, etc.
(4) soil repair materials, key technology and equipment development, integration, demonstration, and management, including: the repair soil environmental friendly materials and preparation methods, selection, structural characterization and function indicators, repairing effect, stability and risk assessment, soil resources comprehensive management after repair, repair materials and biological repair resources comprehensive utilization and safe handling, complete sets of key technology in the integration, demonstration and popularization and application, etc.
(v) research and development of green and environment-friendly bioremediation, joint restoration, in-situ restoration, restoration based on environmental functional restoration materials, rapid site restoration based on equipment, decision support system for soil restoration and post-restoration evaluation, etc. In soil pollution mechanism research and the actual repair case based on the analysis of the integration, gradually form of heavy metals, pesticides, remobilised, radioactive nuclide, biological pollutants, emerging pollutants and its composite soil bioremediation technology system, establish a soil remediation technology standard, evaluation standard and the management policy, to promote the marketization of soil environmental remediation technology and industrialization development, promotion of this emerging industry in China in the international environmental restoration in the market competitiveness.
